Description
また、本発明に係るボンディング装置において、ボンディング対象は、基板に搭載されたチップであって、搬送機構は、基板に搭載されたチップを保持し、ボンディング用ステージまたは表面処理用ステージに搬送し、ボンディング処理部は、ボンディング用ステージに保持されたチップに対しボンディング処理を行い、プラズマ処理部は、ボンディング処理部で処理されるチップと同種類であるが別のチップであって表面処理用ステージに保持されたチップに対し表面処理を行い、制御部は、ボンディング用ステージのチップと表面処理用ステージのチップにおいてそれぞれボンディング処理と表面処理とを同時並行的に行わせる制御をすることが好ましい。
また、本発明に係るボンディング装置において、ボンディング対象は、完成LSIが配列された完成ウェーハであって、搬送機構は、完成ウェーハを保持し、ボンディング用ステージまたは表面処理用ステージに搬送し、ボンディング処理部は、ボンディング処理として、ボンディング用ステージに保持された任意の完成LSIのボンディングパッドに対しワイヤをボンディングしてバンプを形成し、プラズマ処理部は、ボンディング処理部で処理される完成LSIと同種類であるが別の完成LSIであって表面処理用ステージに保持された完成LSIに対し表面処理を行い、制御部は、ボンディング用ステージのチップと表面処理用ステージのチップにおいてそれぞれボンディング処理と表面処理とを同時並行的に行わせる制御をすることが好ましい。
また、本発明に係るボンディング装置において、酸化ガスによって異物を除去する表面処理条件と、還元ガスによって酸化膜を除去する表面処理条件に応じて、表面処理ガスを酸化ガスと還元ガスとの間で切り換える切換手段を備えることが好ましい。
また、本発明に係るボンディング装置において、制御部は、ボンディングキャピラリの先端の位置とプラズマキャピラリの先端の位置を較正した上で、ボンディングキャピラリとプラズマキャピラリの両者の移動制御を同じシーケンスで同時に実行させ、ボンディングキャピラリの先端の移動とプラズマキャピラリの先端の移動とを同じとして、同種類であるが別の個体である各ボンディング対象の同じ部位においてそれぞれボンディング処理と表面処理とを同時平行的に行わせる制御をすることが好ましい。
これに対し、同じ処理ステージ上で、同じボンディング対象の個体について、表面処理とボンディング処理とを連動して行うことも可能である。図9は、1つのXYZ駆動機構102、1つのアーム103、1つの処理ステージ106を備える1ステージ型のワイヤボンディング装置100の構成を示す図である。これと比較する意味で、図1のワイヤボンディング装置10を2ステージ型と呼ぶことができる。以下において図1と同様の要素には同一の符号を付し、詳細な説明を省略する。
